Consensus as a goal for summarization.
When the summarization problem contains multiple input texts,
intuitively the frequently held or common information across
them is one important signal for summary worthy content.
Multi-document news summarization has exploited frequency
from early times [1]}, [2]} to most
recent ones [3]}. Recent work has also used consensus
as a goal for summarizing scientific publications
around health topics [4]}, and identify
agreement and discrepancies in Wikipedia document clusters [5]}.
